transforms
transforms
Presence SIP messages often have extra parameters in the URI header after the user-id@domain. In
order to ensure that these extra parameters do not cause the search rules to fail to match, a ‘.*’ is
appended to pattern strings.

For example, where to reach a Lync user1@test-customer.com the video endpoint calls user1@test-
customer.com
customer.com
The documentation above specifies the required configuration to allow calls and presence to be routed
when the video network device calls the Lync endpoint’s registered name to call it.

For example, where to reach a Lync user1@test-customer.com the video endpoint calls

user1@lync.domain
If a search rule has been created with a domain name transform, for example to allow callers to dial
user1@lync.domain as well / instead of user1@test-customer.com, an additional search rule with a
pattern string for the raw domain (in this example .*@test-customer.com.*) must be added to allow
presence messages through (Lync Server requests that the presence Notifies are sent to the Lync
Server ’s raw domain).

Allowing calls to the raw domain as well as the pre-transform domain is also useful for endpoints
supporting dial back to caller. The calling party’s caller identity will contain the raw domain information.
